Application filed May 27,

T 0 all whom it may concern." M

Be it known that I, Join? J. idnnvnc, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Billiard Cues, Ferrules, and Tips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to billiard cues and has for its object to provide therefor, a ferrule and tip detachably held thereby, and to this end, generally stated, the invention consists of the novel devices and combination of devices, hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings;

Fig. 1 is an elevation of the billiard one having the invention embodied therein;

Fig. 2 is a fragmentary view with some parts sectioned on the line 2-2 of Fig. 1 on an enlarged scale;

Fig. 3 is a fragmentary View with some parts sectioned on the line 33 of Fig. 2;

Fig. 4 is a perspective view of the ferrule and tip, separated, the one from the other; and

Fig. 5 is an end elevation of the ferrule with the movable jaw open, as shown in Fig. 4.

The numeral 6 indicates a billiard cue and the numeral 7 indicates the improved ferrule rigidly secured to the cue by forming, in the inner end thereof, a bore 8 to receive a pin 9 formed on the end of the one by circumferentially reducing the same. The diameter of the cue, at the ferrule, and said ferrule are the same, so that their surfaces, at the joints therebetween, are perfectly smooth.

Integral with the outer end of the ferrule 7, is a segmental jaw 10 and co-operating therewith, is a segmental jaw 11, on the bottom of which, is an inward and radially projecting guide bar 12 slidably mounted, in a radial seat 13 formed in the ferrule 7, said guide bar 12 having dove-tail interlocking engagement with its seat 13. To operate the movable jaw 11 and hold the same set, there is provided a screw 14 turnably 1921. Serial No. 473,204..

mounted in a radial bore 15 which extends into the inner end of the seat 13. This screw 14 has screw threaded engagement with the guide bar 12 and its head is countersunk in the ferrule 7 and is thereby held against inward endwise movement. The external diameters of the jaws 10 and 11, when closed, are the same as the ferrule and form a continuation thereof. l/Vithin the jaws 10 and 11, is an annular groove 17 affording an annular flange 18, the outer face of which is flush with the outer end of the ferrule 7.

Referring now to the improved tip 19, the same is semi-spherical in form and provided with an annular groove 01' channel 20 which affords an annular flange 21 of less diameter than the diameter of the tip 19. The channel 20 is of such diameter as to receive and snugly hold the flange 18 and the channel 17 is of such diameter as to receive and snugly hold the flange 21. Obviously, the interlocking engagement of the flanges 18 and 21 with the channels 20 and 17, respectively, is such as to securely anchor the tip to the ferrule 7 without the use of ad hesives. It will be noted that the diameter of the tip 19 is the same as the ferrule 7 at the joint therebetween.

In applying the tip 19 to the ferrule 7, the screw 14 is operated to open the movable jaw 11 to permit the tip 19 to be interlocked with the ferrule 7 by a radial movement to carry its flange section into the channel 17 and to cause its channel section 20 to receive the flange 18. Then by turning the screw 14 to the right, the movable jaw 11 may be closed to carry its section of the flange 18 to enter the tip channel 20 and to cause its groove section 17 to receive its tip flange 21 and thereby complete the interlocking engagement of the tip 19 to the ferrule 7.

From the above description, it is evident that. by means of the ferrule aws 10 and 11, a tip may"be very easily connected to a billiard one and securely held and, when worn out, can be readily removed and a new one substituted therefor, without loss of time.

What I claim is 1. The combination with a billiard cue, of a ferrule applied thereto and having a fixed jaw and a co-operating movable jaw, said movable jaw having a guide bar forming a radial extension thereof and slidably mounted in a radial seat in the ferrule, a feed screw mounted in the ferrule and having screw threaded 1 0 mounted in a radial seat in the ferrule, a

feed screw mounted in the ferrule and having screw threaded engagement with the guide bar for operating the movable jaw and holding the same closed, said guide bar and seat having dove-tail interlocking engagement, and a tip detaehab-ly held by said aws.

In testimony whereof I affix my signature.
